fd18a452be init: set ro.boot.avb_version in recovery mode
Previously we set ro.boot.avb_version during the first stage mount in normal mode:
  - https://android-review.googlesource.com/#/c/371774/

As the first stage mount is not performed in recovery mode, we need to set the
property separately in recovery mode.

Bug: 37414003

Test: first stage mount /vendor with vboot 2.0 (avb) on bullhead in normal mode
Test: first stage mount /system with without verity on bullhead in normal mode
Test: checks ro.boot.avb_version is 1.0 on bullhead in recovery mode

Test: first mount /vendor with with vboot 1.0 on sailfish in normal mode
Test: checks ro.boot.avb_version doesn't exist on sailfish in recovery mode

d262017fef init: moving early mount logic into init_first_stage.cpp
Also renames "early mount" to "first stage mount" to prevent confusion
with "mount_all --early", which is run in the init second stage.

Also creates a base class: FirstStageMount and two derived classes:
FirstStageMountVBootV1 and FirstStageMountVBootV2 to replace/refactor
existing functions:

   - early_mount() -> DoFirstStageMount() and FirstStageMount::DoFirstStageMount()

   - vboot_1_0_early_partitions -> FirstStageMountVBootV1::GetRequiredDevices()
   - vboot_2_0_early_partitions -> FirstStageMountVBootV2::GetRequiredDevices()

   - vboot_1_0_mount_partitions ->
       FirstStageMount::MountPartitions() and
       FirstStageMountVBootV1::SetUpDmVerity()

   - vboot_2_0_mount_partitions ->
       FirstStageMount::MountPartitions() and
       FirstStageMountVBootV2::SetUpDmVerity()

30a6f276fd init: clean up the SectionParser interface and Parser class
Remove the dependency on Action and Service from what should be a
generic Parser class.

Make ActionParser, ImportParser, and ServiceParser take a pointer to
their associated classes instead of accessing them through a
singleton.

Misc fixes to SectionParser Interface:
1) Make SectionParser::ParseLineSection() non-const as it always should
have been.
2) Use Rvalue references where appropriate
3) Remove extra std::string& filename in SectionParser::EndFile()
4) Only have SectionParser::ParseSection() as pure virtual

Document SectionParser.

Make ImportParser report the filename and line number of failed imports.

Make ServiceParser report the filename and line number of duplicated services.

Test: Boot bullhead

012c573e26 init: Stop combining actions
In the past, I had thought it didn't make sense to have multiple
Action classes with identical triggers within ActionManager::actions_,
and opted to instead combine these into a single action.  In theory,
it should reduce memory overhead as only one copy of the triggers
needs to be stored.

In practice, this ends up not being a good idea.

Most importantly, given a file with the below three sections in this
same order:

on boot
  setprop a b

on boot && property:true=true
  setprop c d

on boot
  setprop e f

Assuming that property 'true' == 'true', when the `boot` event
happens, the order of the setprop commands will actually be:

setprop a b
setprop e f
setprop c d

instead of the more intuitive order of:

setprop a b
setprop c d
setprop e f

This is a mistake and this CL fixes it.  It also documents this order.

Secondly, with a given 'Action' now spanning multiple files, in order
to keep track of which file a command is run from, the 'Command'
itself needs to store this.  Ironically to the original intention,
this increases total ram usage.  This change now only stores the file
name in each 'Action' instead of each 'Command'.  All in all this is a
negligible trade off of ram usage.

Thirdly, this requires a bunch of extra code and assumptions that
don't help anything else.  In particular it forces to keep property triggers
sorted for easy comparison, which I'm using an std::map for currently,
but that is not the best data structure to contain them.

Lastly, I added the filename and line number to the 'processing
action' LOG(INFO) message.

Tom Cherry
98ad32a967 init: handle sys.powerctl immediately
Currently if a process sets the sys.powerctl property, init adds this
property change into the event queue, just like any other property.
The actual logic to shutdown the device is not executed until init
gets to the action associated with the property change.

This is bad for multiple reasons, but explicitly causes deadlock in
the follow scenario:

A service is started with `exec` or `exec_start`
The same service sets sys.powerctl indicating to the system to
shutdown
The same service then waits infinitely

In this case, init doesn't process any further commands until the exec
service completes, including the command to reboot the device.

This change causes init to immediately handle sys.powerctl and reboot
the device regardless of the state of the event queue, wait for exec,
or wait for property conditions.

1a898c25f9 Set libavb version into system property for Treble OTA
Set ro.boot.avb_version to "AVB_VERSION_MAJOR.AVB_VERSION_MINOR".
During Treble OTA match, the major version must be the same as that in
the avb metadata on disk, while the minor version can be equal or
greater to that in the avb metadata on disk.

See how avb versioning work on the following link:

  https://android-review.googlesource.com/#/c/342757/

Also renames AvbHashtreeDisabled() -> hashtree_disabled().

Remove an unneeded search for '/' in get_character_device_symlinks()

nature of FindPlatformDevice().

8bba52fc4b init: support early_mount with vboot 2.0 (external/avb/libavb)
libavb requires verifying AVB metadata on all verified partitions at
once. For example, /vbmeta, /boot, /system and /vendor. We need to
invoke device_init() for those partitions even if we only want to early
mount some of them, like /vendor and /system.

This CL gets all AVB partitions and the early mount partitions from
device tree through "firmware/android/vbmeta" and "firmware/fstab",
respectively. The following is an example to early mount /vendor
partition on bullhead:

firmware {
    android {
        compatible = "android,firmware";
        vbmeta {
            compatible = "android,vbmeta";
            parts = "boot,system,vendor";
            by_name_prefix="/dev/block/platform/soc.0/f9824900.sdhci/by-name"
        };
        fstab {
            compatible = "android,fstab";
            vendor {
                compatible = "android,vendor";
                dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
                type = "ext4";
                mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
                fsmgr_flags = "wait,avb";
            };
        };
    };
};

2ba5c8103d poll umount completion from /proc/mounts
- umount operation is asynchronous except for root partition.
  Returning from umount does not guarantee completion of
  umount. Poll /proc/mounts to confirm completion of umount.
- Treat all devices mounting to /data as emulated devices. This is
  future proof when fs other than sdcardfs is used.
- Drop quota sync from sync step. There is no differences in
  frequencies of quota error.
- Run umount in reverse order from mounting order so that any
  hidden dependency can be auto-resolved.
- Add dump of lsof and /proc/mounts when umount fails. lsof only runs
  when selinux is toggled into permissive mode. The dump is enabled
  only for non-user build.
- Keep logcat until vold shutdown in case vold has any error to report.

bf2dd48241 crash_dump: during early boot, output to kmsg on userdebug.
Crashes that happen before tombstoned is running are extremely hard to
diagnose, because tombstones aren't written to disk, and the window of
opportunity to get logs via `adb logcat` is small (potentially
nonexistent).

Solve this by adding a world-writable /dev/kmsg_debug on userdebug
builds, and writing to it in addition to logcat when tombstoned hasn't
started yet.

53089aa25c init: Use std::string for write_file()
The content parameter of write_file() previously took a char* that was
then converted to a std::string in WriteStringToFd().  One unfortunate
effect of this, is that it is impossible to write data that contains
'\0' within it, as the new string will only contain characters up
until the '\0'.

This changes write_file() to take an std::string, such that
std::string::size() is used to determine the length of the string,
allowing it to contain null characters.

Also change the path parameter of read_file() and write_file() for
consistency.

Lastly, add a test for handling strings with '\0' in them.
